 There exist ways to run Fabric with older versions - modded or vanilla, but they're currently non-trivial or unofficial - see the expert FAQ for more details.
+==== It says that I need to install fabric but I'm already running it! ====
+By 'fabric' it is referring to the [[https://www.curseforge.com/minecraft/mc-mods/fabric-api/files|Fabric API]] mod.
+==== How do I see a list of mods in-game? ====
+Fabric doesn't come with a mod menu built-in. There's a mod called [[https://modrinth.com/mod/modmenu|Mod Menu]] that adds it. Many mods integrate with Mod Menu for in-game configuration screens. Click on the "Mods" button and select the mod you want to configure; if the mod integrates with Mod Menu, you'll see a "Settings" button on the top-right.
 ==== Where can I download published Fabric mods? ====
-They are most often on [[https://www.curseforge.com/minecraft/mc-mods?filter-game-version=2020709689%3A7499&filter-sort=2|CurseForge]] or [[https://modrinth.com/mods?g=categories:%27fabric%27|Modrinth]]. Some mod authors may upload their mods to other sites such as GitHub, GitLab or their own site. See [[https://fabricmc.net/wiki/player:tutorials:adding_mods|Adding mods]] for more information.

 ===== Interoperability =====

+==== Can Fabric run together with Bukkit/Spigot/Paper/Sponge? ====
-Not at the moment. This may change by the end of the year, but is unlikely to be officially supported.
+No, and it is unlikely to be officially supported. This is due to many core differences between Fabric and Bukkit/Spigot/Paper/Sponge.
+If you really want to run plugins on Fabric, you can try the unofficial [[https://github.com/CardboardPowered/cardboard|Cardboard]] mod, but beware that it is incompatible with many mods and doesn't support the complete Bukkit/Spigot/Paper API.
 ==== Can Fabric run together with Forge? ====
@@ Line 96: / Line 102: @@
   * Fabric does not work on top of Forge.
   * It is theoretically possible to create a way to do so - that is to say, there are no known major technical obstacles in accomplishing such.
-  * There were some experiments and discussions done in this regard (as of 30th June), but nothing usable by end users or mod developers.
-The development team does not consider Forge interoperability a high-priority goal, as our focus in our limited time dedicated to the project is on supporting the Fabric community and its developers and users.

Neither are officially supported or recommended.
 ==== Can Fabric run together with OptiFine? ====
-Consider using an OptiFine alternative, as unofficial mods such as OptiFabric may not be compatible with your mods.
+Consider using [[community:optifine_alternatives|alternatives to OptiFine]] like Sodium and Iris, as unofficial mods such as OptiFabric may not be compatible with your mods.

+In particular, OptiFabric 1.14.25 is currently incompatible with Architectury API and Replay Mod.
-[[https://lambdaurora.dev/optifine_alternatives/|LambdAurora's OptiFine alternatives]]
+==== I only have OptiFabric and OptiFine and Minecraft crashes on launch! ====
+This is because OptiFabric 1.13.25 and below are incompatible with Fabric Loader 0.15.0 and above. This is why you'll see ''java.lang.NoClassDefFoundError: net/fabricmc/tinyremapper/IMappingProvider'' in your log. You'll need to use Fabric Loader 0.14.25.

+==== Text has been replaced by squares/tofus when I add Fabric API to my 1.20.1 instance with OptiFabric 1.13.25 ====
+If you're using OptiFabric 1.13.25 for compatibility with Architectury, you'll need to use Fabric API 0.85.0 as it was incompatible with Fabric API 0.86.0 and above.
+==== OptiFabric crashes on my 1.18.2 or 1.19.2 instance when I add Fabric API to it ====
+OptiFabric is currently incompatible with Fabric API 0.77.0. You'll need to use Fabric API 0.76.1.
 ==== Oh no! I've tried enabling shaders on OptiFine and my world looks all weird! ====
-Fabric's rendering patches, while as minimally invasive as possible, make some assumptions about the data format used internally by the vanilla rendering system. Shaders break this assumption, so things go awry. Workarounds do exist and are implemented by the most recent versions of said unofficial mods.
+Fabric's rendering patches, while as minimally invasive as possible, make some assumptions about the data format used internally by the vanilla rendering system. OptiFine breaks this assumption, so things go awry. You should use [[https://modrinth.com/mod/iris|Iris]] instead.
 **DO NOT** downgrade Fabric API as a workaround for this. It's a bad idea.
-==== Can Fabric run together with Sponge? ====
+==== My instance with Sodium and Continuity crashes when gravel/sand falls or when a piston extends ====
+This is because Sodium 0.5.x and earlier do not support the Fabric Rendering API, which is used by many mods, including Continuity. This is why you'll see ''java.lang.NullPointerException: Cannot invoke "net.fabricmc.fabric.api.renderer.v1.Renderer.meshBuilder()" because the return value of "net.fabricmc.fabric.api.renderer.v1.RendererAccess.getRenderer()" is null'' in your log. Add the [[https://modrinth.com/mod/indium|Indium]] mod to resolve this.
+==== Text has been replaced by squares/tofus in my instance with Sodium ====
+This is usually because you have Sodium 0.5.x and below and do not have Indium, or because your versions of Iris and Sodium do not match.
+==== My mods aren't being loaded! ====
+  * Make sure you do not use the Essential Installer or Iris Installer. You can get those mods from Modrinth and CurseForge and put them in your mods folder like any other mod. Use the [[https://fabricmc.net/use/installer/|Fabric Installer]] to get Fabric Loader.
+  * Make sure your mods are located in the "mods" folder in your game directory. The default mods folder on Minecraft Launcher for Windows is "%appdata%\.minecraft\mods".
+  * Make sure you have the Fabric versions of mods.
+  * Check your log or Mod Menu to see which mods are loaded.
+  * Check that Fabric is loaded by checking the bottom left corner of the title screen, or your log.
+      * If it's vanilla, re-run the Fabric Installer. Make sure you're launching the Fabric installation and that the version of the installation is Fabric Loader.
-Not at the moment. Sponge does not yet have a ready API or a working implementation for 1.14, the Minecraft version that Fabric runs on.
